JAMES M. BERRIER, OF EYRIE, TEXAS.

PUMP.

SPECIFICATION forming part of Letters Patent No. 619,534, dated February1 4, 1899.

Application filed April 1 9, 18 9 8.

To all whom it may concern:

Be it known that LJAMES M. BERR1ER,a citizen of the United States,residing at Eyrie, in the county of Ellis and State of Texas, haveinvented certain new and useful Improvements in Pumps; and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,whichform a part of this specification.

My invention relates to that class of pumps which may be operated bymeans of steam or other power applied to a plunger-rod or piston-rod,and has reference particularly to the cylinder and valves of the pump.It consists in a cylinder and piston by which the fluid is drawn andforced in a continuous stream and in valves therefor, all of new andnovel form and combination and arrangement of the several elements,whereby I provide a simple, effective, durable, and economical pump, aswill be more fully described here inafter and claimed.

My object is to provide a pump which may be cheaply and convenientlyconstructed by the use of only such tools and facilities as are found insmall or isolated shops and which may also be readily repaired by assimple means.

My aim is to particularly improve the parts which usually in other pumpscause considerable trouble and delays when parts have to be repaired orrenewed, and this is accomplished in my invention, which is of suchconstruction that ordinary non-ex pert attendants may repair it.

Referring to the drawings, in which like letters of reference designatethe same parts in the different views, Figure 1 represents a sideelevation of a pump constructed in accordance with myinvention; Fig. 2,an end elevation; Fig. 3, a front view of the piston; Fig. 4, a verticalcentral sectional view of the piston; Fig. 5, a front view of thepackingexpanding devices applied to the piston; Fig. 6, a view of theinside surface of the piston follower-plate; Fig. 7, a front or insideview of the piston-head; Fig. 8, afront view of the pistonfollower-plate; Fig. 9, an elevation of Serial No. 678,104. (No model.)

i v the expanding ring; Fig. 10, an elevation of the packing-expander,and Fig. 11 a side view of a section of the expanding ring.

The cylinder Amay be cast and, if desired, have a brass or copper liningand has a straight central bore. It is well adapted to be made of apiece of pipe or tubing without special tools and has at each end aflange a, which may be either cast integrally or otherwise secured.Suitable legs I) b ora stand is secured to the cylinder by suitablemeans. Each end of the cylinder is closed by a suitable head securedthereto by suitable bolts, the head A having a packing-box l3 andpacking-nut B through which the piston-rod B works, and both heads A andA have a suitable portopening, to which is connected aport-pipe A eithercast integrally with the head or formed of a pipe nipple and elbow, eachof these having a union 0 for readily disconnecting when it is desiredto remove a cylinder-head. To each union is connected a suitable line ofpipe, in which are arranged four ordinary checkvalves, so disposed thattwo valves shall be at each side of the inlet or suction and dischargepipes, thus operating with one end of the cylinder, while two valves aresimilarly situated to operate with the opposite end of the cylinder,this arrangement being shown in the drawings, in which 01 designatespipe-nipples of suitable length, 8 designates elbows, and f designateTs. The valves are designated as D E F G, the first two being connectedto a T h, to which the'suction or well pipe S is connected, and the twolatter being connected to a T 'i, to which the discharge pipe is isconnected. ,In connectingv the yoke-like arrangement of pipes and valvessome of the parts may have right and left hand screwthreads,or unionsmay be suitably interposed, as desired, to render a connectionpracticable. The valves and pipe and fittings may be convenientlyobtained in the open market.

The course of the fluid or water is indicated by the arrows upon theelbows, and the checks are set with their tops Z upward, as is usual,and so that the fluid shall enter each one and pass through thevalve-openin g'from the bottom, as indicated by dotted lines upon eachvalve.

The piston B is so constructed that it may be easily packed and kept inclose contact loo N to receive dowel-pins u, protruding from the rearside of the sections of the expanding ring L, so that the latter cannotrotate. The ring L is made in sections having lapped ends 1) w, andoutside of this is placed soft packing K, of hemp or other suitablematerial. Each of the sections has a swelled portion or lug L. collarbored to fit over the piston-rod between the plates on and n and isrevoluble thereon. It has lugs M, having eccentric-shaped faces, whichare in contact with the swelled faces L, so that when rotated in onedirection the ring L may contract, and an opposite rotative movementwill expand the ring. Protruding from the front side of the expander isa pin 25, to which is connected the eye of the bolt R, the pin and boltworking in a recess J in the inner face of the follower-plate n. Thelatter has a slot I, in which a threaded nut T, working upon thethreaded end of the bolt R, also works, being accessible by a wrench foradjustment through the slot, the latter being covered by a removableplate P, secured by suitable screws toprevent fluid entering the pistonwhen in use. The outer end of the rod B is slightly reduced in diameterto form a shoulder against which the follower n, having a hole 0, isforced by the nut H, which is provided with screw-threads, as is the endof the rod B. Thus the plate n-is prevented from rotating on the rod. Amovement of the nut T causes a rotation of the expander M, and thusexpands or contracts the ring L, according to the direction of movement.

In operation when the piston B is moving from the head A to A fluid willenter the cylinder through valve D, the valves E and F being closedwhile the fluid is being forced from the opposite side of the pistonthrough valve G. When the piston moves in the opposite direction ,thefluid is forced out through valve F, valve D being closed, and fluidenters the opposite end of cylinder through valve E, check G being alsoclosed.

I am aware that the valves and pipe-fittings are not in themselves new,and I do not so claim them; but I am not aware that such a combinationhas been used whereby a pump The expander M is in the form of a may beconstructed from such readilyattainable parts as are embodied in myinvention and so well adapted for being quickly renewed at isolatedplaces when worn out.

It is immaterial what power is applied, as the rod B may be continuedinto a steamcylinder or to any lever power device.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a pump, the combination of the cylinder A having a circular boreof uniform diameter therethrough and provided with the supporting-legs,the heads secured to the ends of said cylinder, the piston working insaid cylinder and having the connecting-rod working through one of saidheads, the elbow connected to the outer side of each of said heads, theunions connected to said elbows adjacent to said heads, the elbow 6connected to each of said unions, the T f connected to each of saidelbows e c, the check-valves D E connected at one end to said Ts and attheir opposite inlet ends to the suction-pipe, the check-valves F, G,connected at their inlet ends to said Ts and at their opposite outletends to the discharge-pipe, and the intermediate elbows and nipples,substantially as shown and described.

2. In a pump, the combination with the cylinder and piston-rod, of thepiston consisting of the plate m secured to said rod and having therecesses N in the inner face thereof, the plate n secured to theextremity of said pistonrod in proximity to said plate m and having therecess J in the inner face thereof, the sectional expanding ring Lprovided with the projections L and interposed between said plates, theflexible packing K around said ring, the dowels a on said ring andengaging said recesses N, the expander M interposed between said platesand within said ring and revoluble on said piston-rod and provided withthe lugs engaging the projections on said ring, the pin projecting fromthe side of said expander and the adjusting bolt and nut connecting saidpin, said bolt working in said recess J and said nut working in a slot Iin said plate 11, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
